# Description:
Spiky polygon syndrome; the only workaround I found is using the "VU XGKick Hack" in Emulation Settings > Gamefixes.
Here's the additional tests I did and their results:
Changes to the EE/FPU "Clamping mode" alone have no effect;
Changes to the EE/FPU "Round Mode" alone have no effect;
EE/IOP interpreter/recompiler have the same effect;
superVU recompiler alone has no effect;
Changes to the VU0/VU1 "Clamping mode" alone has no effect;
Changes to the VU0/VU1 "Round Mode" alone has no effect;
The DX9 and DX11 renderers have an additional problem - vertical black bars with artifacts - which the OpenGL renderer can fix using the "Hardware depth" option.

Seems like it. Without it I get polygons being streteched and getting in my view. It's good to know an old hack can be used to solve this.
I'd rather have accurate emulation everywhere without any hacks, but I understand that it would be more inefficient than what we have right now...bummer.

But you can't use the gamefixes for the entire demo, because they might ruin the experience of other games on the disc.

I did check the wiki entry on that game before posting the bug report. There are no testing reports in it, despite your thread. The way I do it is that in the absence of info on the wiki and github, I submit a report. I really don't want to be searching the forum as well.
What I'm willing to do is to check the GameIndex.dbf file on github. If you go look at it right now, you'll see this:

Two other instances of the same game, one doesn't have a compat rating and the other one is marked as playable, even though you and I both know it will probably need the XGkick hack too.
Someone owning one of those versions will get bugs, they'll check the the wiki and might do what I did again.

Also, what do you mean by silly? Do you mean "demo disc" should be dropped from the title? Because I'm about to file another bug report about "Conflict: Desert Storm" using the same demo disc.
It's marked as playable by the wiki, the GameIndex.dbf also calls it playable, yet I'm seeing flashing textures using any renderer.
